/**
 * @file
 * Implementations of token module hooks for the core comment module.
 *
 * The token module requires specific hooks to be added to modules
 * so that those modules can return data about their objects to the
 * token API.  Until and unless token becomes a part of core, the
 * implementations of the token hooks for core modules are provided
 * in the token module itself.
